Kees Cook fbd126f5a6 gcov: annotate struct gcov_iterator with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute.  Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct gcov_iterator.
